Summary: Ubiquitous projection or "display everywhere" is a popular paradigm,
according to which regular rooms are augmented with projected digital content
in order to create immersive interactive environments. In this work, we revisit
this concept, where instead of considering every physical surface and object as
a display, we seek to determine areas that are suitable for the projection and
interaction with digital information. After determining a set of requirements
that such surfaces need to fulfil, we describe a novel computer vision-based
technique to automatically detect rectangular surface regions that are deemed
adequate for projection and mark those areas as available placeholders for
users to use as "clean" displays. As a proof of concept, we show how content
can be adaptively laid out in those placeholders using a simple tablet UI.

Summary: We present SleeD, a touch-sensitive Sleeve Display that facilitates
interaction with multi-touch display walls. Large vertical displays allow
multiple users to interact effectively with complex data but are inherently
public. Also, they generally cannot present an interface adapted to the
individual user. The combination with an arm-mounted, interactive display
allows complex personalized interactions. In contrast to hand-held devices,
both hands remain free for interacting with the wall. We discuss different
levels of coupling between wearable and wall and propose novel user interface
techniques that support user-specific interfaces, data transfer, and arbitrary
personal views. In an iterative development process, we built a mock-up using a
bendable e-Ink display and a fully functional prototype based on an arm-mounted
smartphone. In addition, we developed several applications that showcase the
techniques presented. An observational study we conducted demonstrates the high
potential of our concepts.

Summary: As a novel class of mobile devices with rich interaction capabilities we
introduce tPads -- transparent display tablets. tPads are the result of a
systematic design investigation into the ways and benefits of interacting with
transparent mobiles which goes beyond traditional mobile interactions and
augmented reality (AR) applications. Through a user-centered design process we
explored interaction techniques for transparent-display mobiles and classified
them into four categories: overlay, dual display & input, surface capture
and model-based interactions. We investigated the technical feasibility of such
interactions by designing and building two touch-enabled semi-transparent
tablets called tPads and a range of tPad applications. Further, a user study
shows that tPad interactions applied to everyday mobile tasks (application
switching and image capture) outperform current mobile interactions and were
preferred by users. Our hands-on design process and experimental evaluation
demonstrate that transparent displays provide valuable interaction
opportunities for mobile devices.

Summary: We present Contact Augmented Reality (cAR), a form of AR where a mobile
device with a transparent display rests on top of the augmented object. cAR is
based on the notion that interactions with digital content are enriched by the
tangibility of physically moving a device on and off the augmented object. We
propose and implement three categories of cAR interaction techniques:
contact-based, off-contact and content-aware. We built two cAR prototypes and
explore how cAR can be applied to the domain of active reading. A first
low-fidelity prototype, consisting of an interactive tabletop and transparent
acrylic tangibles, allowed us to iteratively design and test interaction
techniques. The second and higher-fidelity prototype, called a tPad, uses a
semi-transparent touch-enabled 7" LCD display that is placed on top of back-lit
paper documents. The tPad uses an external camera and feature matching
algorithms to identify the document and to determine its location and
orientation. We report on user feedback and elaborate on the salient technical
challenges for cAR devices.

Summary: In many cases, Tangible User Interfaces allow the manipulation of digital
content with physical objects recognized by an interactive tabletop. Usually,
such tangible objects are made of opaque wood or synthetic materials, thereby
occluding the display. In this paper, we systematically investigate the
promising potential of tangibles entirely made of transparent or translucent
materials. Besides visualizing content directly below a manipulable tangible,
transparent objects also facilitate direct touch interaction with the content
below, dynamic illumination and glowing effects. We propose a comprehensive
design space for transparent tangibles on tabletops based on a thorough review
of existing work. By reporting on our own experiments and prototypes, we
address several gaps in this design space, regarding aspects of both
interaction and visualization. These include the illumination of tangibles as
well as the precise input with transparent tangibles for which we also present
the promising results of an initial user study. Finally, benefits and
shortcomings of transparent tangibles are discussed and resulting design
considerations are presented.

Summary: Tangible Windows are a novel concept for interacting with virtual 3D
information spaces in a workbench-like multi-display environment. They allow
for performing common 3D interaction tasks in a more accessible manner by
combining principles of tangible interaction, head-coupled perspective, and
multi-touch techniques. Tangible Windows unify the interaction and
representation space in a single device. They either act as physical peepholes
into a virtual 3D world or as physical containers for parts of that world and
are well-suited for the collaborative exploration and manipulation of such
information spaces. One important feature of Tangible Windows is that the use
of obtrusive hardware, such as HMDs, is strictly avoided. Instead, lightweight
paper-based displays are used. We present different techniques for canonical 3D
interaction tasks such as viewport control or object selection and
manipulation, based on the combination of independent input modalities. We
tested these techniques on a self-developed prototype system and received
promising early user feedback.
